Some semiconductor (solid state) devices can be damagedeasily by static electricity. Such components commonly arecalled Electrostatic Sensitive (ES) Devices. Examples of typicalES devices are integrated circuits and some field-effecttransistor-sand semiconductor "chip" components. Thefollowing techniques should be used to help reduce theincidence of component damage caused by electrostaticdischarge (ESD).1. Immediately before handling any semiconductorcomponent or semiconductor-equipped assembly, drain offany ESD on your body by touching a known earth ground.Alternatively, obtain and wear a commercially availabledischarging ESD wrist strap, which should be removed forpotential shock reasons prior to applying power to the unitunder test.2. After removing an electrical assembly equipped with ESdevices, place the assembly on a conductive surface suchas aluminum foil, to prevent electrostatic charge buildup orexposure of the assembly.3. Use only a grounded-tip soldering iron to solder or unsolderES devices.4. Use only an anti-static solder removal device. Some solderremoval devices not classified as "anti-static (ESDprotected)" can generate electrical charge sufficientto damage ES devices.5. Do not use freon-propelled chemicals. These can generateelectrical charges sufficient to damage ES devices.6. Do not remove a replacement ES device from its protectivepackage until immediately before you are ready to install it.(Most replacement ES devices are packaged with leadselectrically shorted together by conductive foam, aluminumfoil or comparable conductive material).7. Immediately before removing the protective material fromthe leads of a replacement ES device, touch the protectivematerial to the chassis or circuit assembly into which thedevice will be installed.CautionBe sure no power is applied to the chassis or circuit, andobserve all other safety precautions.8. Minimize bodily motions when handling unpackagedreplacement ES devices. (Otherwise hamless motion suchas the brushing together of your clothes fabric or the liftingof your foot from a carpeted floor can generate staticelectricity sufficient to damage an ES device).2 WARNING2.1.
